    如<a class="elementLinkWithType" href="./../../../rup/guidances/concepts/focus_continuously_quality_82DFE946.html" guid="_pRxKsDq0EdqvoMTMKvbIlA">Concept: 持续关注质量</a>中讨论的那样，质量并不是一个易描述的简单概念。同样地，当我们的注意力转向测试讨论以明确质量时，没有一个观点可说明质量是什么或如何评估它。
</p>
<p>
    在 NUP 中，我们使用 <b>FURPS+</b> 模型 <a class="elementLinkWithUserText" href="./../../../rup/customcategories/references_56F06DFD.html#GRA92" guid="7.755968586980351E-308">[GRA92]</a> 来将质量分类:
</p>
<ul>
    <li>
        功能
    </li>
    <li>
        可用性
    </li>
    <li>
        可靠性
    </li>
    <li>
        性能
    </li>
    <li>
        可支持性
    </li>
    <li>
        +（及其他）
    </li>
</ul>
<p>
    这与 NUP 中用于需求的分类方案是相同的（在<a class="elementLinkWithType" href="./../../../rup/guidances/concepts/requirements_62E28784.html" guid="4.582668643506599E-305">Concept: 需求</a>中对此有述）。
</p>
<p>
    对于这些因素中的每一个，应在一个或多个不同级别的测试（请参阅<a class="elementLinkWithType" href="./../../../rup/guidances/concepts/types_of_test_8AB94831.html" guid="1.6037730846300355E-307">Concept: 测试类型</a>）过程中实现和执行一个或多个单个类型的测试（请参阅<a class="elementLinkWithUserText" href="./../../../rup/guidances/concepts/levels_of_test_8A878577.html" guid="1.3136078304677094E-305">技术：测试阶段</a>）。
